“This has been life changing”


Over 480,000 people have signed up for our free two-week keto low-carb challenge. You’ll get free guidance, meal plans, recipes, shopping lists and troubleshooting tips – everything you need to succeed on a keto diet.

Here are new fantastic stories from people who’ve taken the challenge:


Dear Andreas,

I lost about 6 lbs (3 kg) in the two weeks. I am a woman aged 50 who has an underactive thyroid and I have struggled with keeping weight off especially the last five years. I started a lower-carb lifestyle several months ago with good, but slow results.

I am also peri menopausal, which would seem to be against me losing weight. I have adopted an exercise programme also, but I am definitely going to keep eating the ‘keto’ way as the results are fantastic and I feel great. Most women told me I would not loose weight until after menopause especially with an underactive thyroid. How wrong they are! I have also signed up to be a member.

Kind regards,
Karen, South Coast UK

This has been life changing. I am staying on the keto diet as a lifestyle. Too many in my family have diabetes. I don’t want to follow in their footsteps.


I’ve just finished the two-week challenge and I can honestly say it didn’t disappoint! I lost 9 lbs (4 kg), never felt hungry and the food was amazing! I’m just about to join the Air Force and needed to drop a few kilos quickly.

I had never done keto because I never had enough information and was a bit scared to try it, but this website makes it so easy!!! Everything and anything I need to know is there, whether it’s in writing or in video form! The food is absolutely amazing, I never knew how amazing cabbage could taste! Instructions and portions were so great to have! I’m so happy with my results and can’t wait to continue feeling this amazing with all the other wonderful and tasty recipes!!

My name is Genna, I’m 27 and live in Sydney Australia.

Thank you, Diet Doctor!!!

Awesome!! It has helped me so much. I’ve lost five pounds since I started, but 25 pounds total doing a low carb before I discovered Diet Doctor. I recommend it 100%!


I loved the low-carb challenge! I had been trying ketogenic on my own; the low-carb challenge simplified the process significantly for me through menu guidance. I love to cook and found the recipes simple, quick and delicious. I also found I dropped weight easily which is nothing short of miraculous for a women in her fifties. I’m a convert to the low-carb lifestyle.
